Abstract: A parking lock arrangement for an electromotively driven motor vehicle, including a parking lock wheel which is rotationally conjoint with respect to a shaft in the drive train and which has multiple cutouts, a lock element which is movable between a locking position and a release position along a movement path and which, in the locking position, engages in a form-fitting manner into a cutout of the parking lock wheel and, in the release position, is out of engagement with the cutouts of the parking lock wheel, a parking lock actuator which is operatively connected to the lock element and wherein the lock element is adjustable between the locking position and the release position along its movement path. The movement path of the lock element can be rectilinear.

Abstract: A central release mechanism for a pneumatic clutch actuating device has a cylinder housing, which, about a central axis, delimits a ring-shaped pressure chamber wherein a ring-shaped piston which can be pneumatically pressurized via the pressure chamber and which is operatively connectable to a clutch is guided so as to be displaceable along the central axis. In the pressure chamber, between the ring-shaped piston and a base of the cylinder housing, a preload spring arrangement braces the ring-shaped piston and the cylinder housing apart from one another. A movement of the ring-shaped piston relative to the cylinder housing is detectable with a sensor arrangement which has a position detector and a position encoder. The preload spring arrangement has a multiplicity of distributed preload springs, angularly spaced apart from one another, about the central axis.

Abstract: A method and arrangement controls a regulating variable which determines the rotational speed difference of a clutch by selecting a phase with a curve of the regulating variable specified by a time function during a transient clutch condition. The beginning and the end of this phase are fixed by one or two influencing variables which are specific to the vehicle. One of the influencing variables is determined by the accelerator pedal actuation and another variable is determined by the clutch temperature.
